“We visited the Desert Museum 34 years ago and going back now we were not sure what to expect, but...it was better than we remembered it. It's part Desert park, a zoo and garden full of all southwestern flora. Eat lunch there it was great!”

Exhibits: Pollination Gardens

Birds, bees and butterflies are the stars of these gardens. The Hummingbird Aviary is a scene of constant action as the tiny, iridescent "jewels of the desert" dart and hover so closely you can feel the air disturbed by their wings! In breeding season, nets are near enough to sneak a peek at the babies! Bring your cameras as the birds seem to pose for photos! The aviary is a marked contrast to the lovely Pollination Garden outside, where butterflies and bees float and drone peacefully between blossoms.

Hummingbird Aviary Background

When we first opened the Arizona-Sonora Desert Museum's hummingbird aviary,
we had no idea whether or not any of the seven species of the birds on exhibit
would breed and rear young. Since opening day, however, we've seen Costas, Broad-billed,
Black-chinned, Anna's, and Calliope hummingbirds nest, lay eggs, and rear young.
There have been a total of 114 nests built, 186 eggs laid, 116 birds hatched,
and 102 birds fledged. No other zoological institution can boast of such success!

But this success has not come without a good deal of effort on the part of
the exhibit keepers and the hummingbirds - especially when it comes to nest-building.
For example, in 1992 we renovated the exhibit, clearing out all the plants and
expanding and replanting the new space. Within a month of the renovation, several
hummingbirds began to build nests.

The nests were loose and quite fragile, and
even experienced nesters were having difficulty. Most of the nests fell apart
and we lost several eggs that fell out and broke. We scratched our heads for
days trying to figure out the problem before we finally concluded that a primary
component of hummingbird nests was missing spider webs!

Hummingbirds use spider
webbing as a way to bind and tie their nests together. The spiders had yet to
reestablish themselves in the spanking new exhibit. I immediately went out and
collected webs from around the grounds, rolling them up on twigs, which I left
in the aviary. I also collected 25 labyrinth
spiders and introduced them. Within days the spiders were weaving their webs
in the aviary and the birds' nests immediately improved.
